Abstract : Task 1 of this study consisted of a design study of the possible application of the Boeing JT3D quiet nacelle to the current DC-8 short duct and long duct domestic aircraft fleet as exemplified by the DC-8-61 and DC-8-63 aircraft. The Task 1 study identified many physical and functional problems associated with the use of the Boeing quiet nacelle on DC-8 aircraft. Of the configurations studied, two configurations for the DC-8-61 and two configurations for the DC-8-63 were selected for cost evaluation. The configurations selected for each of the two DC-8 models were identified as Family I and Family II. During the conduct of the Task 1 study, it appeared that Douglas discrete nacelles should also be studied to determine the most advantageous approach from an overall cost standpoint.
